I have a site, and it's big, 50K categories and like 450K products. I'm running a level 3 VPS with Hostgator to hopefully ensure I have enough power. It's not terribly slow, but slow. 6 seconds plus on some pages.
I have an included system info, firebug page slow info, and debug info (attached) for page http://www.urbanposters.com/index.php/shop/art
, my largest category, below. My questions:
- Does an optimizer like JCH Optimizer help a lot for problems like these?
- Are the large number of queries, 217, the issue?
- Is it worth the money to buy The Speedbooster, info here http://codingmall.com/products-mainmenu-8/65-speed-up-virtuemart
- Do you have any insight from your experience on strategies I can employ to speed this site up?
